High Voltage Protection Refurbishments

Replacement of obsolete primary protection and auxiliary relays associated with long established substation switchgear sites

Provision of new microprocessor protection relays fitted and prewired off site to panel fabricated fascias. This minimises system feeder overall outage periods for installation, testing and commissioning

Design and installation work content established at each substation. Existing protection relay wallframes or free standing panels surveyed to determine the extent of metalwork replacement and agree protection relay layout. Installation methodology determined for sequence outage of panels at all substations. Cable supply and installation work associated with protection and supervisory control finalised

Fabricated panel metalwork comprising full panel front plates, relay projection collars or replacement panel doors fitted out with protection relays and control components. Each assembled unit prewired and wiring point to point tested in readiness for site installation
